We report σ-hole interaction/spodium/tetrel bonding and other non-covalent interactions in a heteronuclear Pb(ii)–Salen coordination polymer using DFT, HSA, QTAIM/NCI, and QTAIM/ELF plots. The non-covalent interactions predominantly drive the formation of extended architectures.

Abstract Two new cadmium (II) complexes, viz., [Cd4(L1)2(ƞ1-NCS)2(µ2-ƞ2:ƞ1-OAc)2] (C1) and [Cd4(L2)2(µ1,1-N3)4]n (C2) (H2L1= N, N’-ethylene bis(3-methoxysalicylaldimine), H2L2= N, N’-ethylene bis(3-ethoxysalicylaldimine) were impeccably synthesized and structurally characterized using various sophisticated analytical techniques including SCXRD. X-ray diffraction confirmed complexes possess Cd4 structural motifs with two distinctive geometrical arrangements displayed around the central Cd (II) ion. Supramolecular architecture and multi-dimensional polymer formation reunited through the utilization of all anionic forms of ligands taken after by bridging bolster of pseudo-halide ions. Supramolecular interactions are more easily discernible through Hirshfeld surfaces and fingerprint plots. Herein, we demonstrated the potential role of the as-synthesized complexes towards the antimicrobial and anticancer activity. To address the issue, compounds are tested for antibacterial and antifungal activities against the bacteria Staphylococcus aureus (ATCC 25923), Bacillus subtilis (ATCC 6635), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), and fungal Candida albicans (ATCC 10231). The antimicrobial screening revealed that C1-C2 demonstrated higher action over ligands (L1-L2), thus, simply signifies the endowment of the compound's structural environment on these biological movements. Further, compounds anticancer activity was determined against A549 (Human lung carcinoma) and Panc-1 (Human pancreatic) lines using MTT assay. Molecular docking was performed to correlate the experimental binding results between complexes and the targeted proteins responsible for bacterial or cancerous features. Herewith, E. coli enzyme MurB (PDB ID: 2q85 ), B. subtilis SMC head domain (PDB ID: 5h67 ), cyclin-dependent kinase 2-associated protein 1 (PDB ID: 2kw6 ), and Epidermal Growth Factor Receptor (EGFR) tyrosine kinase domain (PDB ID: 1m17 ) have been selected to identify the true binding modes and docking poses, which are responsible for this superior biological activity. Subsequently, the current research puts in an exertion to crack a new Cd (II)-mediated complex as an antibacterial and anticancer drug which may demonstrate to be a moo fetched pharmaceutical.

A detailed study of Cu2+ion affinities of the amino acids namely Glycine (Gly), Alanine (Ala) and Cysteine (Cys) and their Cu2+complexes have been investigated using density functional theory. Interactions of a Cu2+ ion with oxygen, nitrogen, and sulfur (for cysteine) of the selected amino acids have been optimized. The results show that complex formation reactions are exothermic in both gas and aqueous phase and the neighboring stereochemical nature of Cu2+ion is more or less same in all amino acids. The computed Cu2+ affinity for both O-Cu2+ and N-Cu2+ interaction in the gas phase is in this order ∆ECys>∆EAla>∆EGly. In aqueous phase, Cu2+ion affinity for O-Cu2+ interaction follows the same order as above, whereas in N-Cu2+ interaction it differs as ∆EAla≥∆ECys>∆EGly. In NCu2+ interaction Zwitterterionic complexes (Cu2+ bind with both nitrogen and carbonyl oxygen atom) have been formed. The optimization energies are estimated to be lower relative to the other interactions and the Cu2+ ion affinities have been predicted more. The results have been well supported by the natural population analysis (NPA) of the atoms and hardness parameters. The charge, energetics, geometrical and electronic properties of the complexes signify that the interaction between the Cu2+ with the carbonyl oxygen and the amino nitrogen of free amino acids is predominantly a covalent interaction in the gas phase and which becomes more ionic in the aqueous phase.

ABSTRACT Silver nanoparticles were successfully synthesized from AgNO3 through a reliable, eco-friendly and simple green route using Paederia foetida L. leaf extract as a reducing cum stabilizing agent. UV-Visible Spectroscopy, dynamic light scattering, atomic force microscopy, transmission electron microscopy, and X-ray diffraction analysis were used for characterization of silver nanoparticles. The synthesized silver nanoparticles were spherical in shape with size range of 4–15 nm. The nanoparticles were face-centered cubic crystal structure. The adopted technique for silver nanoparticle synthesis is suitable for large-scale production. The as-prepared silver nanoparticles revealed excellent antibacterial activity against different gram classes of bacteria and would be a promising candidate for various pharmaceutical, biomedical, and environmental applications.
